Testing the pressure in the manifold will tell you if there is any restriction in the inlet, but wont tell you anything about the manifold itself.
I will send the Autocad drawing to you later.
Thanks man, sounds like i need to start shopping for a manifold.
before i start looking the M54B30 is the E39 530 and E46 330 manifold correct?
Do you know if the E46 325 manifold is the same?
